Title: Gas flow measurements
IPC: G01P5/18
Filed: 1972-10-17
Abstract: 1439324 Measuring gas velocity BRITISH STEEL CORP 16 Oct 1973 [17 Oct 1972] 17627/72 Heading G1A The mean velocity of a gas, e.g. the effluent from a steelmaking vessel, is measured by detecting emitted radiation at two points spaced along the flow or determining the delay to the upstream signal necessary to produce maximum correlation between the waveforms. As shown, Fig. 1, the gas flow through a pipe 1 is monitored by two I.R. pyrometers 2, 3 (e.g. PbS photo-conductors) having narrow fields of view which lie in parallel planes but are inclined to one another so as to define a restricted axial path in the gas along which correlation exists and the velocity is determined. The detector signals are passed through identical filters 4 which may be high, low or band-pass selected in accordance with the emission characteristics of the gas and the measurement mode used. The upstream signal is passed through a variable delay network 6 and a circuit 7 derives the correlation junction, the maximum value of which is attained when the delay introduced by network 6 is equal to the 'time of flight' of the gas between the two pyrometers. A circuit 8 calculates and displays the velocity of the gas. For certain applications fast acting AGC amplifiers 4A may be introduced into the signal channels. One or both pyrometers may be mounted for pivotal movement within the crosssectional plane of the pipe in order to scan the effective measurement axis across the pipe to obtain a velocity profile.

Title: Arrangements for regulating a multi-phase non-synchronous machine by means of a commutator regulating machine
IPC: H02K17/38
Filed: 1958-06-03
Abstract: 856,673. Control of A.C. motors. BROWN, BOVERI & CIE A.G. June 3, 1958 [June 3, 1957], No. 17677/58. Class 38 (3). An asynchronous machine A is connected in cascade with a three-phase commutator machine Sch and is regulated by generators G1, G2, which are adapted to provide two phase-displaced excitation components, one controlling the speed and the other the power factor of the machine A. A frequency converter F is connected to the commutator machine through an exciter E, and is excited from the series-connected generators G1, G2, which are driven in synchronism with the supply system RST by motor M, the output of the converter being at slip frequency. Tachometer generators T1, T2 are coupled to the machines A and M respectively so that a difference voltage, proportional to the slip of the machine A, is applied to regulators R1, R2, whereby the stator current of the asynchronous machine tends to follow a predetermined law in relation to the slip. Further quick-acting regulators R3, R4 come into operation when the stator current deviates from its prescribed value, these regulators being controlled through current transformer Wi and voltage transformer Wu. The machine A may be used to drive a converter, or it may be coupled to a flywheel for preventing fluctuations of power or frequency in a power-boosting system.

Title: Improvements in or relating to the manual focusing of photographic enlargers
IPC: G03B27/62
Filed: 1955-06-20
Abstract: 770,846. Photographic enlargers. KIENZLE, P., [trading as KIENZLE APPARATEUND MODELLBAU, P.]. June 20. 1955 '[July 2, 1954], No. 17691/55. Class 98 (1) In a photographic enlarger, means for facilitating the focusing of a negative comprises a test negative disposed out of the plane of the negative, and means for causing'the image of the test negative to be superimposed, when desired, on the image of the negative. As shown, the negative is held between the surface of the condenser lens 5 and ledges 2 formed on the negative carrier. A plate 6, which carries the bellows 7 and has an aperture for the passage of light from the negative, is connected to the housing on the enlarger by bolts 10 entering slots in the plate. A bent up portion of the plate 6 carries a test negative 9, which is illuminated by light passing through the condenser 5, through 'an aperture 11 in the negative carrier, and is reflected by an inclined part of the enlarger housing to illuminate the negative 9. A plate 12 sliding on the plate 6, has a bent up end 13 carrying a mirror 14. To focus the enlarger, the plate 12 is pulled out to its extreme position limited by a stop (not shown) by means of a knob 16, in which position light from the negative 9 is deflected by mirror 14 to the objective lens. The optical distance of the negative 9 from the lens is the same as that of the negative to be enlarged. The image of the test negative appears as a bright area in the middle of the image of the negative to be enlarged. After focusing, the plate 12 is slid forward by means of knob 16, so that mirror 14 is moved out of the optical path, and a lug 15 carried by the plate 12 closes the aperture 11 to prevent the passage of light therethrough.

IPC: C07D295/10
Filed: 1954-06-16
Abstract: b -Dialkylaminoethyl esters of a -alkylphenylacetic acids, of the general formula <FORM:0748064/IV(a)/1> where R is an alkyl group containing 4 to 8 carbon atoms one of which is asymmetric and R1 and R2 are both methyl or both ethyl radicals, and their quaternary ammonium bromides, are prepared by esterification of an a -alkylphenylacetic acid chloride with a b -dialkylaminoethanol, followed by quaternization, if required, with an alkyl bromide.  The a -alkylphenylacetic acid is prepared by alkylation with an alkyl halide RHal of benzyl cyanide in benzene solution in the presence of sodium amide followed by saponification of the resulting nitrile. The invention also specifically comprises a  - 1 - methylpropyl - phenylacetic acid-b -diethylaminoethyl ester, its quaternary ammonium bromides and its acid citrate.  In an example, benzyl cyanide and 2-bromo-butane give a -1-methylpropyl-phenylacetonitrile, which is saponified to the corresponding acid with concentrated sulphuric acid; this is converted to the corresponding acid chloride with thionyl chloride and the acid chloride is esterified with b -diethylaminoethanol. The ester is converted to its methobromide, ethobromide and acid citrate.  The following compounds are prepared similarly: (1) the nitriles corresponding to the formula C6H5.CHR.CN, the radical R being 2-ethylhexyl, 1-methyl-n-butyl or 1-methyl-n-pentyl; and the acids and acid chlorides derived therefrom (in the hydrolysis of a -2-ethyl-n-hexylphenyl-acetonitrile to the corresponding acid, a -2-ethyl-n-hexyl-phenyl acetic acid amide is isolated as a crude intermediate), and (2) a -1-methylpropyl - phenyl - acetic acid - b  - di-methylaminoethyl ester and its metho bromide; a  - 1 - methylpropyl - phenyl acetic acid - b -diethylaminoethyl ester iso-buto-bromide; a -2 - ethyl - n - hexyl - phenyl acetic acid - b -diethylaminoethyl ester; a -1-methyl-n-butylphenyl acetic acid-b -diethylaminoethyl ester; a  - 1 - methyl - n - pentyl - phenyl acetic acid-b -diethylaminoethyl ester and the corresponding dimethylaminoethyl ester.

Title: Improvements in or relating to the cleaning of sparking plugs
IPC: H01T21/04
Filed: 1953-06-26
Abstract: 740,281. Cleaning sparking plugs. QUEENSTOWN ENGINEERING CO., Ltd., and SALES, F. J. June 25, 1954 [June 26, 1953], No. 17845/53. Class 7(4) In apparatus for cleaning sparking plugs of the kind comprising a chamber not shown, provided with a manifold 11 having a number of jets 10 which direct cleaning liquid on to the plugs in the chamber, a two-way valve 18 is provided for shutting-off the liquid supply to the manifold and connecting the latter to a supply of compressed air. An electrically driven centrifugal pump 14 draws the cleaning liquid from a container 12 and supplies it via pipes 16, 17, the valve 18 and manifold 11 to the jets 10; the valve handle it subsequently moved to the dotted-line position to disconnect the supply of liquid to the jets 10 and admit cool or heated compressed air thereto from entry to the nozzle injection chamber 9 but opens a return passage 12 for the fuel, and in another position blocks the return passage 12 but opens the entry to the nozzle chamber 9. The fuel is supplied from a tank 1 by a pump 3 and flows through a heater 4 to the injection pump 6 which, during normal operation, delivers it through a passage 8 to the chamber 9 for injection past the valve 10. Prior to starting the engine the valve 7, actuated either manually or, as shown, by compressed air acting upon a piston, is moved down to block the passage 8 and open a passage 11 leading through the injector body to the return passage 12 whereby the fuel heated in the heater 4 is circulated through the injector body to warm it. To start the engine, the valve 7 is raised to open passage 8 and close the passage 11. The valve 7 may be built into the injector as shown or disposed at any point between the pump 6 and injector chamber 9 and if several such valves are provided for one engine they may all be controlled from one point. The passage 11 may comprise several passages passing through different parts of the injector. by bolts 9. The bolts 9 also hold in position a guard plate 8, which limits the valve movement, and a curved spring 6 of the same shape as the plate 3 and having arms 7, equivalent to the arms 5, bolted by the bolts 9. A third bolt 11, which also holds the guard 8 in position, acts as a guide for the plate 3 and spring 6 which have a notch 12 surrounding the bolt. The spring 6 is arranged so that when the valve is closed a small clearance is left between it and the guard 8. In a modification, Fig. 6, the spring 6 is curved towards the valve and the arms 7 extend in opposite directions, a small clearance existing between the spring and the valve when the valve which is of the same form as the spring 6, is closed.

Title: Improvements in or relating to statistical or calculating machines
Filed: 1930-06-10
Abstract: 356,304. Statistical machines. BRITISH TABULATING MACHINE CO., Ltd., Victoria House, Vernon Place, London. -(Assignees of Daly, G. F. ; Johnson City, New York, U.S.A.) June 10, 1930, No. 17855. Convention date, June 11, 1929. [Class 106 (i).] Total-taking.-In a statistical or calculating machine, in which amounts from a register are transmitted to a receiver (printer or accumulator) through a reading-out device, the latter consists of selecting commutators each connected to a separate denomination of the register and connected in turn to denominations of the receiver through a single emitting commutator which acts synchronously with the movement of the receiver parts (e.g. the type bars). The invention is described as applied to a record-card-controlled statistical machine of the kind set out in Specification 247,200, [Class 106 (i), Calculating &c.] ; 10, Fig. 1, being the tabulating motor (TM) circuits, 11 the resetting circuits, GC the group-control circuits, and UB and LB the upper and lower brushes. When a lower brush energizes a countermagnet 12, the latter closes contacts 13 for the printing magnet 14 (listing). Each counter wheel 17, Fig. 2, is geared to a selecting commutator 22 (totalling) having segments 23 and a brush member 24 on the gear wheel 25 so that the brushes occupy a position according to the number on wheel 17. One brush will be on a segment 23 and the other on a common conductor 31 on the selecting commutators. All the segments 23 corresponding to the same digit are connected in parallel to a common conductor 32, Fig. 1. These commutators end in brushes 64 which coact with the spots 63 on the emitting commutators 60, the spot 63 being connected to a common conductor 62 and brush 65. 60 is on the total-taking shaft of the machine and is rotated, but only at totalling, in synchronism with the rise of the type bars past their holding pawls which are released to engage the bars as the printing magnets 14 are energized when the spot 63, corresponding to the position of each brush 24, reaches a brush 64. Hence the brushes 24 are pre-set according to the total on the counter and all type bars are arrested differentially by one rotation of the emitting commutator 60. Contacts 71 are only closed at totalling to connect commutators 22 to their magnets 14, by a magnet 72 in circuit with a cam 73 on the total-taking shaft. Specification 280,935, [Class 106 (i), Calculating &c.], is referred to.

IPC: C10G1/00
Filed: 1929-06-11
Abstract: 313,879. I. G. Farbenindustrie Akt.- Ges. June 18, 1928, [Convention date]. Hydrogenation, destructive.-Viscous oils suitable for use as lubricating or Diesel oils and hydrocarbons of low boiling point are obtained from liquid carbonaceous materials under mild temperature conditions, e.g. about 400‹ C., with hydrogen under pressure so that the asphaltic constituents are reduced and the solid paraffins are not destroyed, separating off the fractions, and then, if necessary, after separation of the paraffins, cracking or destructively hydrogenating the residues to obtain products of low boiling point. Brown coal distillation tar is treated with hydrogen at 380‹-400‹ C. and 200 atmospheres pressure in presence of a catalyst containing molybdenum and zinc. The unchanged solid paraffins are separated by centrifuging from the liquid products, which are then distilled under a pressure of 15 m.m. The fraction distilling between 180‹-300‹ C. is separated and amounts to about 15 per cent of the total liquid product. This fraction after further refinement, if necessary, has the properties of a good machine oil. The residues are destructively hydrogenated or cracked to obtain low boiling point products'.

Title: Control mechanism for a fuel injection pump
IPC: F16H59/30
Filed: 1961-05-16
Abstract: 980,081. Regulating. BORG-WARNER CORPORATION. May 16, 1961 [May 25, 1960], No. 17895/6 Heading FIB. [Also in Division F2] A control mechanism for a fuel injection pump for an I.C. engine having an air-intake manifold, comprises a movable member for controlling the output of the pump, a manifold vacuum operated servomotor for moving the member, a reference vacuum operated servomotor for moving the member for compensating for changes in ambient pressure, and a vacuum pump for operating the reference vacuum servomotor. The depression created in an air intake manifold 14, Fig. 1, of an I.C. engine is communicated through a conduit 46 to the left side of a spring-pressed diaphragm 42 which is subjected to atmospheric pressure on its right side. Variation in these pressures causes the diaphragm 42 to move a shaft 21 and a cam 20, guided by arm 22, longitudinally. The cam surface 26 acts on a roller 35 to rotate an arm 24 about a pivot 34 and raise or lower a shaft 25 of a fuel injection pump to vary the pump output. A port 45 is connected to an air bleed mechanism (not shown) to adjust the effect of manifold vacuum on the diaphragm 42 to modify the pump output for certain engine conditions. To prevent the manifold vacuum from completely overruling the effect of the air bleed, a restriction 47 is provided in the conduit 46. A spring-pressed diaphragm 52 is subjected on its left side to atmospheric pressure and on its right side to a reference vacuum produced by a pump 15 driven at constant speed as by a motor 16. Thus variations in atmospheric pressure produce longitudinal movement of a shaft 56 and a cam 23 to cause a roller 32, connected to arm 22, to roll along the cam surface 33 and thereby rotate the arm 22 with the cam 20 about a pivot 31. The combined effect of the diaphragms 42 and 52 on the position of the cam 20 compensates for variations in atmospheric pressure. An alternative embodiment is shown in Fig. 2 in which the manifold vacuum and reference vacuum diaphragms 132 and 142 respectively, are of the same diameter and arranged so as to cancel out the forces exerted by atmospheric pressure. Both diaphragms are connected through a common shaft 144 to a modified output shaft mechanism 111 in which the guide arm 122 is rigidly secured to the machine casing by screws 125 and 126. A further embodiment (not shown), which may employ actuating mechanism as at 111 in Fig. 2, has a single diaphragm exposed on opposite sides to the manifold vacuum and reference vacuum. A diaphragm 74 Fig. 1, acted on by the manifold vacuum through conduit 80 and a diaphragm 73 acted on by the reference vacuum through conduit 78, jointly actuate a pivoted lever 76 which, for example, may operate the ignition advance and retard mechanism of the engine and control a valve of an automatic gear-box. In applications in which it is desired to compensate for atmospheric pressure variation only, the diaphragm 74 and related structure may be eliminated.
